PART 2

The astronauts left the main part of the spaceship and went inside the lunar module, 1which had been fitted with its own oxygen tank. But inside the smaller module, 2which was designed to hold only two people, carbon dioxide levels started rising. The astronauts, 3 who had been following instructions from the ground crew, made special filters out of plastic bags and cardboard. Then they waited in the cold and dark while the ground crew, 4 who were working 24 hours a day, tried to work out a way to bring them home. If some people in America were losing interest in the Space Program, the Apollo 13 crisis, 5 which was discussed on all the TV news programmes, changed all that. The astronauts 6 who were risking their lives and the people 7 who were trying to save them all became national heroes - especially when Apollo 13 returned safely to Earth with all three astronauts alive.

The Apollo 13 mission is often described as a 'successful failure' because while the mission did not achieve its primary goal of landing on the moon, the mission became a triumph of human ingenuity and teamwork in the face of crisis. Despite the explosion that damaged the spacecraft and the many challenges faced by the crew and the ground crew during the mission, all three astronauts returned safely to Earth, thanks to the remarkable efforts of everyone involved.

(Sứ mệnh Apollo 13 thường được mô tả là một "thất bại thành công" bởi vì mặc dù sứ mệnh không đạt được mục tiêu chính là hạ cánh trên mặt trăng, nhưng sứ mệnh này đã trở thành một chiến thắng của sự khéo léo của con người và tinh thần đồng đội khi đối mặt với khủng hoảng. Bất chấp vụ nổ làm hỏng tàu vũ trụ và nhiều thách thức mà phi hành đoàn và nhân viên mặt đất phải đối mặt trong nhiệm vụ, cả ba phi hành gia đã trở về Trái đất an toàn nhờ những nỗ lực đáng kể của mọi người tham gia.)
